What is the reasons why greenhouse effect and ozone layer depletion are considered two-related serious environmental concerns in the 21st century

Explanation:

gases such as carbon dioxide and methane are considered to be greenhouse gases.they play a vital role in trapping the heat of the sun

thats why...there is no much temperature change between day and night.

but  certain industrialisation based human activities have increased the amount of greenhouse gases in our atmosphere resulting in the increase of global worldwide temperature.

usage of refridgerators and air conditioners have resulted in the release of chloroflurocarbons(CFC's). These gases basically eat up the ozone layer.This is known as ozone depletion.

the sun releases harmful ultraviolet rays which cause skin cancer.The ozone layer plays a vital role in acting as an umbrella.

This depletion has increased the number of patients suffering from skin cancer.

The ozone depletion and global warming increase the global temperature.If this continues,the human species will become extinct

the answer is c i just put d and i got it wrong so yeah its d
